§ Proof of the Finiteness of Modular Covariants, these Transactions, vol.14 (1913), p. 300.* It is to be noted that there is not necessarily any such invariant of degree d + p" -1, nor of degree d + 2 (p" -1 ), etc.For example, if I be unity, the only homogeneous formal invariants congruent to I for values of x and y in the field are 1 and powers of Q = h.In this case thare are no invariants I>, I¡, •••,/".
